Forschungszentrum Julich has taken the leadership of a consortium responsible for the design of the High-Energy Storage Ring (HESR), which is part of the FAIR project at GSI [1]. Within these activities a design for a short cosine-theta superconducting dipole has been carried out together with industry partners. Its length will be approximately one third of the original HESR dipole, whereas all other design parameter will be the same. The main design criterion is the small bending radius of 15.3 m of the magnet implying that the coil itself has a curved shape. Besides the geometrical design of the cold mass, this paper focuses particularly on the finite element calculations from the assembly through the cool down to the operating temperature of the magnet. First manufacturing tests as well as a report on the achievements so far are presented.
